python操作redis数据库的三种方法

pip3 install redis

import redis
r = redis.Redis(host='127.0.0.1', port=6379, db=1, password=None, decode_responses=True)

import redis
pool = redis.ConnectionPool(host='127.0.0.1', port=6379, db=1, max_connections=100, password=None, decode_responses=True)
r = redis.Redis(connection_pool=pool)

pip install django-redis

CACHES = {
  "default": {
    "BACKEND": "django_redis.cache.RedisCache",
    "LOCATION": "redis://127.0.0.1:6379/0",
    "OPTIONS": {
      "CLIENT_CLASS": "django_redis.client.DefaultClient",
      "CONNECTION_POOL_KWARGS": {"max_connections": 100},
      "DECODE_RESPONSES": True,
      "PSAAWORD": "",
    }
  }
}

from django.core.cache import cache # 结合配置文件实现插拔式
# 存放token，可以直接设置过期时间
cache.set('token', 'header.payload.signature', 300)
# 取出token
token = cache.get('token')
